JDBC批量删除某一用户下的触发器

从另外一个地方导出来的表，再导入的时候，存在百把几十个触发器，用PL/SQL删老是报触发器不存在的异常，但是呢，用SQL查能查出来，删也能删掉。

决定用JDBC的循环来删这些。。。。

public static void deleteTriggers() throws SQLException {
        Connection connection = getConnection();

        List<String> triggerNameList = new ArrayList<String>();
        String sql = "SELECT  TRIGGER_NAME  FROM ALL_TRIGGERS WHERE OWNER='NJZJLMS'";//OWNER后的一定要大写，否则查不到东西
        Statement st = connection.createStatement();
        Statement st2 = connection.createStatement();
        ResultSet rs = st.executeQuery(sql);
        while (rs.next()) {
            String triggerName = rs.getString("TRIGGER_NAME");
            if (!triggerName.contains("=")) {
                triggerNameList.add(triggerName);
            }
        }
        System.out.println("triggerNameList:" + triggerNameList.size());
        String sql2 = "";
        for (int i = 0; i < triggerNameList.size(); i++) {
            System.out.println("triggerName:"+triggerNameList.get(i));
        }
        for (int i = 0; i < triggerNameList.size(); i++) {
            sql2 = "drop trigger \"" + triggerNameList.get(i) + "\"";//这里triggername一定要用双引号，单引号无效
            System.out.println("sql2:"+sql2);
            st2.execute(sql2);
        }
        st.close();
        rs.close();
        connection.close();
    }
